Question

Im having this problem where my Label2 which is assigned to be a text doesn’t appear on the Jframe, even though I added it. Im assuming the other Labels which I set as images are overlaping it? If that is the problem how would I go upon fixing it?

        SwingUtilities.invokeLater(new Runnable() {

                try {
                    final Generator frame = new Generator();
                    frame.setVisible(true);
                } catch (final Exception e) {

                label.setIcon(new ImageIcon("data/hover_b.png"));
            }

            @Override

                label.setIcon(new ImageIcon("data/hover_a.png"));
            }

        });

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setPreferredSize(new Dimension(295, 358));
        setTitle("test");
        getContentPane().setLayout(null);
        setResizable(false);
        setVisible(true);
        setIconImage(img.getImage());
        getContentPane().add(label);
        getContentPane().add(label1);
        getContentPane().add(label2);
        pack();
    }
}

Answer 1

You’re calling setVisible(true) before adding all your components. Don’t do this. The orde is:

• add your components
• call pack()
• call setVisible(true)
• if later you make changes then call revalidate() on the container, then repaint()
